I started a blog a few days ago. So far I've managed to get it indexed and getting some traffic to it. But I'm not making anything off of adsense yet. One reason for this is the adsense ads suck. It's a blog of random funny videos and images with a little bit of commentary from me. So if I throw up a video with a dog in it all my adsense ads are now for dog food. I'm not really surprised no one is clicking on these. Is there a way (one that wont get me banned) to add different key words to my posts that the reader wont see but that will change my ads?
